SuSpenSion SySTemS. SuBJeCT: Concepts and Functions. LiT no: T15001. Air dump (or exhaust) valves increase stability during trailer loading. Lets say I was pulling an empty spread axle trailer. Could I activate the air dump valve so that I could save wear and tare on the front axle of the.
Personal, i would just run dual dump vavles(elctric). 2 different toggle switches on the dash.
One front one rear. Add a second pig tail( just make it using a car trailer kit x2 cheaper) this way you can dump out your axle for turning(helps save tires and makes turning and backing of that spread easier) than when you need to drop the bags just flip both and dump out both bags. You would be amazed where you can get a trailer working between the front and back axles. Plus when i ran flat i did alot of coils so i could dump the bags and stop that bag hop up when they rip that coil off the deck. Pm me if you want i can tell you what all you would need and have to do to add this setup. Personal, i would just run dual dump vavles(elctric). 2 different toggle switches on the dash.

I ran a separate 7wire pigtail to the trailer already. All of the 7 wires come up into the dash but I only have one attached within the trailer for the current dump valve. My need though is more for an automatic dump when the emergency line empties.My buddy's Benson has this, so I know they do make a valve.just not sure what I need to do for my current setup (minimally) to accomplish this.I might put a call into the Fontaine dealer in the AM and ask.I'm sure they'd know right off.
